1949threepence

What's his username on here, Pete?

Can't tell you anything about it as I've never been myself. But what I can say is that I won the bid for a very nice virtually BU 1890 penny from LCA in September 2014, for £80 hammer, which was touted as having been bought from Charing Cross Market for £25 - date not given. Charing Cross collector's Market website

Indeed. The lack of it slows so many sites down to a crawl while we wait for endless ads to fully load.

In fairness Pete, we can only call things as we see them at any given moment in time - and in two cases verd has appeared on a slabbed coin, when it was not (apparently) previously there. So I think we are entitled to raise questions as to the degree of care shown in the handling process of slabbing, especially given the other instances of carelessness objectively highlighted by Sword. For example, the tiny piece of plastic pictured lodged in the slab cannot, by definition, be the fault of anyone but the slabbing company. Obviously there is no hard evidence to confirm or deny fault either way when it comes to the appearance of verd, post slabbing, but naturally a certain degree of suspicion pertaining to the slabbing process will be aroused, and it's perfectly proper that such suspicions are given an airing, if only to alert other members as to the possibilities.

Say what?

The 1919KN at the June 2019 LCA gets a fair bit of hype in the write up, but in reality isn't a brilliant strike, on either side.

Getting a decent strike, as opposed to just nominally UNC, is the real toughie with the H's and KN's - especially the H's. I'be been incredibly lucky with three of the four, with the 1918H still outstanding

Well I've managed to locate and buy one in "mid" grade. £19.95 and issue free. The scarcity is probably akin to the 1879 narrow date penny. Not that difficult in VF and below, but incredibly tough in EF and above.

Bit disappointing from the penny enthusiast's point of view, although there's a very nice Freeman 1 on offer for someone. You can forgive the carbon spots on such a rare coin There is, however, another penny which I might go for as a meaningful upgrade. Interesting that the estimates on the UNC 1902 LT penny have gone up substantially on the one they put up for bid in the March auction, and I won with a £240 bid. Probably because the bids were well above the estimates then. Although the specimen now on offer isn't as good as the March one, which was virtually flawless. As well as the carbon spot which they mention, there are also a number of other very visible tiny spots, on the obverse especially.

Well it does seem a remarkable co-oincidence for one to suddenly pop up after 70 years, post slabbing.

Indeed - sounds as viable a possibility as any. Interesting topic.

Thanks. I do know that "carbon spots" (be that a misnomer or otherwise) are very common on bronze/copper coins which are close to uncirculated. Often multiples on the same coin, some tiny, others much larger. They seem to disappear if the coin is circulated - a process I know obviously occurs, but I've no idea what the explanation is. Nor why they never seem to appear on coins once circulated. Does the handling of circulation and the build up of other matter on the coin's surface lend some protection against this, I wonder? Whereas verd can appear on any coin, circulated or not. ETA: Interesting article Another observation (please feel free to correct me if I'm wrong, as I'm manifestly no expert on this topic) - verd seems to be contagious to other coins in contact, whereas "carbon spots" don't. Nor does a single carbon spot spread to other areas on the same coin, unless a separate incident occurs, unconnected with the appearance of the first. Not as far as I'm aware anyway. So there does seem to be a significant difference between the two, both in scope and effect?

Ah, now that's interesting. I know that saliva droplets cause carbon spots to develop. So why - scientifically speaking - would one droplet of saliva cause a carbon spot, and another cause verd to develop?

You mentioned his name on a PM you sent on 19th April, Pete. But there was no telephone number.

That would be consistent with Gouby's explanation. Do Golbourn coins have a website? I did do a search, but couldn't find them. Maybe the name spelling is adrift?

Right.......... ...........So anyway thanks for the very useful link. For me the relevant bit was this:- 1944 to 1946 - Officially dark toned by 'Hypo' However some survived with varying degrees of lustre by being trapped between other coins!

As the base of the 4 is broader than the tooth, you could look at it either way - over a tooth, or over a gap between teeth. What's the significance of that anyway?

I'm wondering if this is one:-

I'd agree with that. I use Chrome and ad blocker quite compatibly.

Possibly, but not definitely it would appear. Doing a bit of research and it would appear that despite the "no slabbing of verd coins" mantra, coins with verd still do get slabbed. I'm no chemist so I've no idea the extent to which slabbing protects from the initial development of verd to the point where it becomes visible. Presumably if there are contaminants present when the coin is slabbed, these will subsequently have a deleterious effect on the coin. Bit of a chicken and egg situation.

Thanks Pete - glaring and bad. How could they have missed it?

Just seen this post. No - can you post the pic again, or link to?

Scrubbed - it was my imagination.

Funnily enough, even as I was typing out the suggestion you contacted them, Pete, I thought you might encounter communication issues. I certainly have in almost every recent attempted contact with a major concern. To get a reply with literally just a telephone number on it and no other explanation, or even a few words asking you to call, is a joke. Best most straightforward trading contact I've had in recent years (in any field) was Dave Craddock, who just says "hello" in the old school way when he answers the landline phone. What a refreshing change that made.

Why don't you just ask them Pete?
